The all but indistinguishable contestants of a “Miss Korea” contest have been the subject of considerable attention online, in no small part thanks to Korea’s reputation as a powerhouse of plastic surgery.

With Miss contests and contestants alike already seemingly hailing from a parallel universe, and with Koreans already the most surgically perfected race on the planet, there is not too much surprise about the condition of these girls – although some are some understandably suspicious that they are the same person, or to what extent overzealous Photoshop application has blended an already less than diverse group:

“These are all the same person, right?”

“Quite a hard spot-the-difference there.”

“Mix in an ugly and they’d pass for a typical idol group.”

“They should just identify them by surgeon, good advertising too.”

“Easy trade if you just have to keep giving people the same face like this…”

“They really are all the same, quite freaky.”

“Mass production indeed!”

“Different standards of beauty, perhaps? Japanese AV stars are all surgical creations but they end up looking nothing like this.”

“They were probably all equally ugly to start with.”

“Seriously though, these aren’t all different people are they?”

“They all have the same nose, it’s horrible.”

“Looks like a cheap eroge.”

“At least enter them by surgeon.”

“How would they judge these anyway? By bedding them?”

“They should put up the before photos, the winner is the one who started looking the worst.”

“Who needs Photoshop when you have Korea!”

“They should just change it from beauty contest to plastic surgery contest…”

Yeah but Tenchi was made in a time where artists gave a shit about what they were doing and weren't so fucking lazy before all of this moe shit became ultra poplular. Now artist's just use a generalized face palette to speed things up and make a generic anime/manga to get some money.

Christ, it's not just eye shapes, eyebrows, heights and hair colours that are supposed to be different.

Name an anime with characters that really have realistic variations in design. I mean from face shape and body type to the usual facial features and hair styles. Aside from the token 'fat otaku' guy or such, it'd be pretty difficult to find a show like that.
The whole art style generally suffers from characters having the same basic traits with slight variation, which isn't how real people work at all. and it'd be really hard to pull something like that off, but a lot of anime does it worse than most. To be fair, some do have better anatomy and proportions that others.

I'm not saying it should change or that it's bad, necessarily, just that it's hopeless to expect characters from a show like K-On, where all the main characters are girls in the same age group, having the main purpose of looking cute, to not resemble each other in more than one or two ways.
